No video on Mac Pro 1,1

So I've been repairing a Mac Pro 1,1.

Serial No.: YM75101H0GP

So I originally got it with no video card or HDD, so I bought a EVGA GTX 680 SC Signature and put it in Mac Pro. Additionally, I also followed this video:

https://www.youtube.com/watch?v=0a6tSGUz...

To get a bootable copy of OS X El Capitan on the HDD I am using in it.

The Diagnostic Leds say that the board is getting trickle power, the computer powers on and that the EFI has done loading.

In addition, the Mac Pro does the boot chime and every component seems to be working, however no image is being pushed to the display.

Answer this question I have this problem too

Is this a good question?

The first that usually goes in this machine is the video card.

That being said: Actually look on the machine for the specs on it as the serial number brings up four machines.

On all four:

Pre-Installed MacOS: X 10.4.7 (8K1079) Maximum MacOS: X 10.7.5*
